Prognostic Value of Pulmonary Elastance Methods in HFrEF: A Comparative Study.
BACKGROUND Pulmonary vascular resistance (PVR) is commonly used to quantify right ventricular (RV) afterload in heart failure with reduced ejection fraction (HFrEF), yet it reflects primarily the steady component of pulmonary vascular load. Simplified pulmonary arterial elastance indices may better characterise the int...
